Case of submandibular schwannoma and review of literature

Abstract

Schwannomas are slow growing, benign tumours arising from Schwann cells. They are usually solitary and are sometimes associated with Neurofibromatosis type 1 and 2. As reported by Okada et al., while approximately 25%-40% of extra-cranial schwannomas occur in the head and neck region, Schwannomas of the oral cavity are very uncommon, accounting for only 1% of all Schwannomas. We report a case of a sublingual schwannoma in a 47-year-old female, discovered incidentally during the workup for tinnitus. The radiological and histopathological findings, along with a literature review, are presented.
